There are two types of chokes, one uses the lever and the plunger and the other
type uses a remote cable with a clip-on sealer end. Both work on the same principle
of opening a bypass circuit to let in extra fuel. (So really they are
not chokes at all, but enrichment circuits)
Attached are two pictures, hopefully they are good enough to be self explanatory.
Something we learned last year with the 277 on the Firefly: there is a 3/32" thick
rubber flat surface on the part that seals up against the brass opening for
the bypass. (the "gasket") Part #7 on the remote system, part #8 on the lever
system.
Over time, that rubber can get worn out or damaged, and then it no longer seals,
which means you are now dumping extra fuel in at all throttle settings. Which
makes it impossible to get the engine to jet properly. Once I found the problem
it was an easy fix: grub out the old rubber and grind a sharp edge on the
end of a piece of metal tubing the same diameter as the plunger, punch a piece
of rubber out of any suitably thick rubber scrap and force it into place in the
end of the plunger. All it has to do is allow/stop fuel flow.
As far as how you actually rig it; the nut 3 screws on the adjuster 2, screw the
adjuster into closure 4. Stick the cable through the rubber 1, and down through
the adjuster and out through the closure, slide the spring over the cable,
then the cable goes through sleeve 6, and then hook the end of the cable into
the slot in piston 7. Let the spring snap the sleeve down into place around
piston 7 and it will hold the cable in the piston. Adjusted correctly, actuating
the cable will raise the piston just enough to open the fuel bypass in the
carb.

Forgiving is tough, being forgiven is wonderful, and God's grace really is amazing.
